Topic of the talk: Volume Graphics

A recent trend in volume graphics focuses on the use of the discrete voxel representation for a variety of geometry-based applications. These applications include CAD, simulation, and animation, as well as those that intermix geometric objects with 3D sampled (eg., medical imaging) or computed datasets. In these applications, the inherently continuous 3D geometric model is discretized employing voxelization (3D scan conversion) algorithms, which generate a volume buffer (3D raster) of voxels. In order to render these volumetric models and other volumetric data sets in real-time a special-purpose volume engine, such as Cube-4, is imperative. Several companies have fabricated chips and boards based on the Cube-4 technology. These trends in volume graphics have the potential to revolutionize the field of computer graphics and its applications by offering an alternative to the existing surface graphics, image-based graphics, and point graphics approaches.

Arie E. Kaufman is the Director of the Center for Visual Computing (CVC), a Leading Professor and Chair of the Computer Science Department, and Leading Professor of Radiology at the State University of New York at Stony Brook. He was the founding Editor-in-Chief of the IEEE Transaction on Visualization and Computer Graphics (TVG), 1995-1998. Kaufman has been the co-Chair for multiple Eurographics/Siggraph Graphics Hardware Workshops, the Papers or Program co-Chair for the IEEE Visualization '90-'94, and ACM Volume Visualization Symposium '92, '94, '98, and the co-founder and member of the steering committee of the IEEE Visualization conference series. He has previously chaired and is currently a director of the IEEE Computer Society Technical Committee on Visualization and Computer Graphics. He is an IEEE Fellow, and the recipient of a 1995 IEEE Outstanding Contribution Award, the 1996 IEEE Computer Society's Golden Core Member, 1998 ACM Service Award, and 1999 IEEE Computer Society's Meritorious Service Award. kaufman has recently co-founded Viatronix Inc. to commercialize virtual colonoscopy, a volume visualization technology for assisting doctors in colon cancer screening. He has conducted research and consulted for about 30 years specializing in volume visualization; graphics architectures, algorithms, and languages; virtual reality; user interfaces; and multimedia. He received a BS in Mathematics and Physics from the Hebrew University of Jerusalem in 1969, an MS in Computer Science from the Weizmann Institute of Science, Rehovot, in 1973, and a PhD in Computer Science from the Ben-Gurion University, Israel, in 1977.
